| 摘要 | A device for a rotary haptic interface including: a rotary button and an interaction member interacting with a magnetorheological fluid, the rotary button and interaction member being secured to a shaft for rotation therewith, a chamber defined by walls and containing the fluid and the interaction element, and a mechanism generating a variable magnetic field. The element for interaction with the fluid includes a skirt surrounding the shaft, the skirt being secured to a longitudinal end of the shaft opposite the end to which the rotary button is secured, and extending from the first end towards the rotary button. The shaft passes through a single wall of the chamber and a sealing mechanism is arranged between the shaft and the wall. A mechanism for guiding the rotation of the shaft is arranged around the shaft between the sealing mechanism and the rotary button. | ||||||
